Namhansanseong Fortress

Noh Mun Duek · CC BY-SA 4.0

A mountain fortress that served as Joseon's emergency capital, now the favourite hiking wall of Seoul.

Namhansanseong was raised on the ridges southeast of Seoul as a refuge for the court should the capital fall. In the winter of 1636 King Injo and his ministers held out here for 47 days against the Qing army before surrendering — one of the bitterest chapters in Joseon history. Today the wall follows the crest as a long trail through pine forest; the full circuit takes about four hours. At the foot of the mountain waits a row of restaurants specialising in tofu and mushroom rice, the familiar reward after the climb.
